Latest individual samples: Secchi 8 ft (2026-07-02), chlorophyll-a 12 µg/L (2025-08-31), and total phosphorus 17 µg/L (2025-06-29).
Secchi clarity is how deep a black-and-white disk stays visible from the surface — more feet means clearer water.
Chlorophyll-a is an algae pigment; higher values signal more algae in the water column.
Total phosphorus is a nutrient that feeds algae and aquatic plants. It is not a weed survey — depth, bottom type, water movement, and management change the actual lake experience.

Wisconsin DNR fisheries survey
Fish population survey
Structured LakeList extraction from the 2025 DNR fisheries survey. Population estimates, density, and catch-rate indices use different units, methods, and scopes, so each value is presented in its original form rather than normalized against a different measure.
Survey indicatorsValues keep their source unit and method; unlike measures are not scaled or compared.
Management contextLake-specific 2025 survey combining April-May fyke netting, a whole-lake adult-walleye mark-recapture estimate and six miles of June electrofishing. Gear-specific indices and sample size shares remain distinct.
DNR estimated 2,379 adult walleyes, documented moderate pike/crappie abundance, high muskellunge size quality, similar bass catch rates and improved bluegill size.
- Raster infographic pages 2-3 were rendered at 4x and RapidOCR-assisted; promoted chart values were manually reconciled with species, thresholds, units and narrative context.
- Ambiguous smallmouth quality/memorable percentages and the chart largemouth preferred percentage were excluded; the clear narrative shares remain.
- Natural walleye reproduction remains very low, and the population is primarily stocked.

Depth FAQ
How deep is Sissabagama Lake?
Sissabagama Lake is 48 feet deep at its deepest point, according to Wisconsin DNR records.
Is there a free depth map of Sissabagama Lake?
Yes. LakeList publishes a free interactive depth contour map of Sissabagama Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from C-MAP Genesis community sonar (derived) survey data.
Where does the Sissabagama Lake depth map come from?
The interactive depth contours are derived from C-MAP Genesis community sonar (derived). Each contour set passes a visual QA review against the source document before it is published. The depths are derived from community sonar recordings (C-MAP Genesis Social Map, used with permission), with gaps between recordings interpolated; not for navigation.
